Hi, You can retreive all PTR records using this API call: https:// GM /wapi/v2.6/record tr?_return_fields=ipv4addr,ptrdname,name,zone,ipv6addr,dns_name,dns_ptrdname After that in your script you can filter/aggreagate records as you wish. BR, Vadim

You should open a support case for this; Infoblox support is best positioned to provide advice on appliance recovery. This is especially true if the appliance is currently providing DNS or DHCP service in production.
